This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute ...

A keypad is one of the most commonly used input devices in microprocessor applications. In a standard keypad wired as an X-Y switch matrix, normally-open switches connect a row to a column when ...

The purpose of this project is to demonstrate two forms of digital input – using the button Grove and the tilt switch Grove . Pressing the button will light the LED, and activating the tilt-switch ...

The Arduino UNO R4, released in two versions last year, supports the CAN bus in terms of hardware and software. In this article we look at some handy CAN modules, an experimental setup, and the basics ...

The Arduino Extension is a newly added feature to the OpenPLC editor. It allows Arduino Sketches to be added to and run alongside a PLC program. It supports almost every Arduino library and code that ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [Rick’s] ...
